The delay in commissioning of the Kudankulam Nuclear Power Plant (KNPP) has pushed the project cost up around 14 per cent. When construction began in September 2001, the government had joined hands with Russia for the project, which was then expected to cost Rs 13,600 crore. But according to the government, till January 2013, expenditure on KNPP was Rs 15,454 crore.

Minister of State in the Prime Minister’s Office V Narayanasamy said, the expenditure on Kudankulam Project (KKNPP Units 1&2 – 2 x 1000 Mw) till January 2013 had been Rs 15,454 crore and efforts were being made to commission the first unit in May this year. It may be noted that the project was supposed to go on stream in Sept 2007.

However, the project was in a limbo for a decade due to the political and economic upheaval in Russia after the post-1991 breakup of the Soviet Union. There were also objections from the United States on the grounds that the agreement does not meet the 1992 terms of the Nuclear Suppliers Group (NSG).

Then, the construction began only in September 2001 and the cost was estimated to be $3 billion (around Rs 13,600 crore).

In a statement to the Lok Sabha on Thursday, the minister, said in nuclear power plants, a series of activities including integrated system tests, first criticality, subsequent performance tests, synchronisation of the unit with the grid and raising of power in steps take place.

The nuclear power reactors at Kudankulam employ several safety features to ensure protection of people and the environment even under most stressful situation like extreme natural events leading to a loss of power and cooling water supply, the minister said.
